Title: Desulfurization of heavy petroleum oils
IPC: B01J8/20
Filed: 1960-01-20
Abstract: Heavy petroleum oil is desulphurized by an autofining process in which a finely divided hydrodesulphurization catalyst is slurried in the oil, the slurry is subjected to a temperature of 750-950 DEG F. and a pressure of 50-400 p.s.i.g., and the hydrogen and oil vapour thus formed are repeatedly recycled and redispersed in the slurry, while the slurry is additionally agitated in the reaction zone to make the gas, vapour and slurry mixture homogeneous.  The heavy oil may be topped crude, reduced crude or residual stock boiling mainly above 700 DEG F.  The catalyst may be cobalt molybdate, silica or boron oxide on alumina support or a mixture of vanadium and molybdenum oxides.  Agitation of the slurry may be effected by means of a turbine agitator, or a high speed propeller or impeller. Apparatus for carrying out the process is described, while regeneration of the catalyst is also mentioned.

Title: Process for the production of tertiary butanol
IPC: B01J31/10
Filed: 1963-01-22
Abstract: Tertiary butanol is produced from i-butane by hydration wherein water with an acid cation exchanger containing sulphonic acid group as catalyst suspended therein is reacted in the liquid phase at 50 DEG to 130 DEG C. and at 10 to 30 atmospheres pressure with isobutene in one or more reactors, the mixture is then fed to a separator at reaction pressure to separate into a hydrocarbon layer containing the alcohol, and an aqueous layer in which the catalyst is suspended, the aqueous layer being recycled, still at reaction pressure with make-up water being added, and the hydrocarbon layer is distilled to give the alcohol, containing water dissolved therein, and unreacted hydrocarbon.  The hydrocarbons, which may be a C4 fraction containing i-butene, and water are used in a proportion between 20:80 and 80:20. The aqueous phase may contain 10 to 60% by weight of catalyst of grain size 10 to 250m  and part of the smallest particles may be removed from the recycled aqueous phase.  The reaction may be carried out in the presence of 0.1 to 5 g. per litre of aqueous phase of at least one non-ionogenic or anion active water-soluble emulsifier. These may be recovered from the hydrocarbon phase and added to the recycled aqueous phase.  U.S.A. Specification 2,366,007 and German Specification 908,247 are referred to.

In the circuit shown the output of a tuning fork frequency controlling circuit is applied in push-pull to the control grids where symmetrical limiting of the oscillation amplitude is effected by grid current. The input of the fork circuit is provided from push-pull connections to equal anode loads. The cathode resistor stabilizes the frequency against changes in circuit conditions while adjustment of the grid bias or individual or joint control of the anode loads will provide a small adjustment of frequency.

A stage in a variable gain differential direct current amplifier comprises two matched transistors supplied from a current source via two resistance circuits, the values of which are inversely proportional to the currents flowing through them at a predetermined gain level. According to the invention, means are provided responsive to variations in the gain level and controlling the current source so the ratio of the currents flowing in the resistance circuits remains substantially independent of the gain level. The input stage of a D.C. amplifier comprises transistors 11, 12 having as collector load circuits resistors 61, 62 respectively and adjustable potentiometer 60, and being fed via an auxiliary transistor 57. Input signal is applied to the base of transistor 11 via resistor 22 or 23, the base of transistor 12 being earthed and a common emitter impedance being provided in the form of further auxiliary transistor 13, to the base of which gain controlling potentials are applied. The input stage 11, 12 drives, via resistance/capacitance networks 36, 38 and 37, 39 respectively, the bases of a second stage 70, 71 the collectors of which are coupled in a similar manner to an output stage comprising transistors 75, 90. Negative feedback is applied from the collectors of output transistors 75, 90 to the bases of transistors 70, 71 via resistors 76, 99 respectively. Any unbalanced component in the drive to transistors 70, 71 is detected by means of a potentiometer 33, 34 and applied to the base of transistor 45, whereas the corresponding unbalanced component at the collectors of transistors 11, 12 is detected by means of potentiometer 31, 32 and applied to the base of transistor 46. Transistors 45, 46 have a common emitter circuit resistor 49 and are coupled respectively to transistors 52, 53 which have common emitter circuit resistor 54. Transistor 53 has collector load resistor 56 and is direct coupled to the base of auxiliary transistor 57, to provide degenerative feedback for any unbalanced component.
